IDirectMusicObject8::ParseDescriptor
Given a file stream, the ParseDescriptor method scans the file for data that it can store in the DMUS_OBJECTDESC structure. All members that are supplied are marked with the appropriate flags in dwValidData.
This method is primarily used by the loader when scanning a directory for objects, and is not normally used directly by an application. However, if an application implements an object type in DirectMusic, it should support this method.
Syntax
HRESULT ParseDescriptor(
LPSTREAM pStream,
LPDMUS_OBJECTDESC pDesc
);
Parameters
pStream
Stream source for the file.
pDesc
Address of a DMUS_OBJECTDESC structure that receives data about the file.
Return Values
